The amplification design of injection-molded parts should first control the material temperature and mold temperature, and different brands of plastics must have different temperature requirements, followed by the adjustment and control of pressure and exhaust, and finally the supplementary plastic control of injection-molded parts size is enough. The fluidity of plastic materials is poor, and there will be different situations when two or more mixtures are used. Plastic materials should be controlled within the optimal fluidity range.

The control of mold temperature is more complicated. Injection molded parts with different shapes, sizes and wall thickness ratios have certain requirements for cooling. Mold temperature controls the cooling time to a great extent, so try to keep the mold at an allowable low temperature to shorten the injection cycle, improve production efficiency and change the mold temperature.

The shrinkage rate will also change, the mold temperature will remain stable and the dimensional accuracy will be stable, thus preventing the defects such as deformation, poor gloss and cooling spots of molded parts and making the physical properties of plastics in the best state. Of course, there is also a debugging process, especially the molded parts of multi-cavity molds are more complicated.
